Abstract Solid electrolyte materials composed of lithium titanium phosphate (LTP) or lithium aluminum titanium phosphate (LATP) and ionic liquid (IL) were formed and studied by means of X–ray diffractometry, thermogravimetry, scanning electron microscopy, impedance spectroscopy and density methods. Study revealed substantial enhancement of total ionic conductivity of the studied materials compared to the parent LTP or LATP matrixes. Two components of total resistance were identified. One, independent on the IL contents in the material, was attributed to grains. The second one strongly decreased with the IL contents. It was suggested that interaction of the IL with grain boundary was responsible for that.
